Happi Coat 'Koi Nami'

The happi coat where a koi rides the great wave

Two icons of Japanese water meet on this one. The koi-nami happi coat brings together a dark koi and Hokusai's great wave — the towering blue curl with its clawing foam rising on the sleeve, a small Mount Fuji in the distance, the koi swimming through it all. Movement, sea and legend wrapped around a single jacket.

The blues do the work. The great wave builds in deep indigos and crisp white foam, fading to a pale sky and that tiny far-off Fuji, while the koi adds its own current of motion. It's the most classically 'ocean' piece in the range, and the print floods one sleeve and the back so the wave really seems to move as you do.

As an open happi coat it's made to hang loose and unfastened, draping from the shoulders. The light, firmly woven fabric keeps a clean line, the wide three-quarter sleeves hold the kimono silhouette, and worn open the wave-and-koi scene frames your base layer with all that blue energy.

The blue-on-dark palette is easy to ground. A white tee underneath makes the foam and Fuji pop; dark trousers keep the focus on the water. It's the piece for someone who loves the great wave but wants it woven into a fuller scene — koi, sea and mountain — rather than reproduced on its own.

This is for the person who wants Hokusai's wave brought to life with a koi and Mount Fuji — sea and legend together — on an easy open layer. Wear it open over a white tee with dark trousers and trainers. The free-size cut sits true to size with a relaxed, open drape.
